The ministry has asked the competition authority to provide a general description of competitive conditions for oil companies and their suppliers to answer a question from a member of parliament, it said.
The question from the lawmaker is whether oil firm Statoil (>> Statoil ASA), which is responsible for 60 percent of Norway's oil and gas output, misuses its dominant position over suppliers, the ministry said.
"It is natural to prepare a political discussion about competition conditions on the Norwegian continental shelf on a good factual basis, both on the competition situation and whether us politicians can, or should, do something about it," Industry Minister Monica Maeland said in a statement.
The statement did not say how long this would take.
Last month, BP (>> BP plc) and independent oil firm Det norske (>> Det Norske Oljeselskap ASA) agreed to merge their Norwegian business in a $1.3 billion all-share deal, partly to counter Statoil's dominant position in the sector.
Statoil said it had a common interest with others to have a competitive industry that featured many actors, that it had brought in new operators on the Norwegian continental shelf, and it was responsible for a lesser share of total production than when it merged with the oil arm of Norsk Hydro (>> Norsk Hydro ASA) a decade ago.
"We work closely with the suppliers' industry to do the necessary improvements to make operations more effective, simplify, standardise and industrialise," a Statoil spokesman said.
"To cut costs is a part of ensuring competitiveness," he said, adding that Statoil would help Norwegian authorities if they wanted information from the company.
